I’m super nervous...

Just going over all paperwork and feel overwhelmed.. Lots of changes

That is perfectly normal. I did that the first time around. I actually didn’t show up for my surgery. This time it happened so fast that I didn’t have time to back out. What also helped is me starting a journal of the reasons why.

Have some trust in your more rational self...the self that jumped through a million hoops to get here. When people are faced with stressful, scary situations it's easy to get spooked and want to run. Trust the self who got you here. You knew what you were doing and it's going to be ok:)
